[0002] In the 5G NR (New Radio) system, beamforming is widely used for transmission. The terminal and the base station transmit signaling and data based on the determined beam, and there is a corresponding relationship between the receiving and sending beams of the base station and the terminal. When the terminal measures that the quality of the current working beam channel is not good, that is, beam failure (BF) occurs, it is necessary to initiate a beam failure recovery request (BFRQ) to notify the base station to perform beam failure recovery (BFR) processing.

[0003] NR technology supports terminals working in two types of cells, including primary cells (Pcell) and secondary cells (Scell). The primary cell is the cell that the user equipment (UE) initially accesses, which is responsible for communicating with the radio resource control (RRC) of the user equipment. The secondary cell is added during RRC reconfiguration and is used to provide additional radio resources.

[0004] When beam failure occurs in the secondary cell, the stability of the NR system is easily affected due to the lack of corresponding processing specifications. Summary of the invention

[0031] First, the terms involved in this application are explained:

[0032] NR system: NR system refers to the fifth generation mobile communication system (5th Generation, 5G) led by the 3rd Generation Partnership Project (3GPP), among which enhanced mobile broadband (eMBB), massive machine type communications (mMTC) and ultra-reliable and low latency communications (URLLC) are defined as the main application scenarios of 5G.

[0033] 3GPP introduced the Carrier Aggregation (CA) technology, which supports a larger transmission bandwidth by aggregating multiple continuous or non-continuous carriers. The cells involved in carrier aggregation are divided into primary cells (PCell) and secondary cells (SCell). PCell is the cell that the user equipment (UE) initially accesses, which is responsible for communicating with the radio resource control (RRC) of the UE. SCell is added during RRC reconfiguration and is used to provide additional radio resources.

[0034] Beam failure: The operating frequency of 5G can be as high as tens of GHz. If high-frequency electromagnetic waves cannot be sent in a concentrated manner, the path loss will be very serious. Therefore, the high-frequency signals in 5G can be transmitted using beam forming technology. Since the energy of the signal is concentrated in a certain direction, the original signal beam quality will deteriorate or even become unusable due to factors such as occlusion during movement, resulting in beam failure.

[0035] Figure 1 It is a schematic diagram of the architecture of the communication system, such as Figure 1 As shown, the communication system includes: an access network device and one or more terminal devices, wherein the multiple terminal devices are, for example, Figure 1 The terminal device 1, the terminal device 2, the terminal device 3 and the terminal device 4, etc., the secondary cell beam failure processing method provided in this application can be applied to Figure 1 The access network equipment and / or terminal equipment in the Figure 1 The communication system shown can be applicable to different network standards, for example, it can be applicable to Global System Of Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE) systems and 5G and other network standards.

[0036] Optionally, the above-mentioned communication system may be a system in a scenario of ultra-reliable and low latency communications (URLLC) transmission in a 5G communication system.

[0037] Optional, reference Figure 1 In the above communication system, the access network device and multiple terminal devices communicate through beams.

[0038] Therefore, optionally, the above-mentioned base station can be a base station (Base Transceiver Station, BTS) and / or a base station controller in GSM or CDMA, or a base station (Nodeb, NB) and / or a radio network controller (Radio Network Controller, RNC) in WCDMA, or an evolved base station (Evolutional Node B, Enb or Enodeb) in LTE, or a relay station or access point, or a base station (gNB) in a 5G network, etc., and the present application is not limited here.

The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with the radio access network. For another example, the wireless terminal can also be a personal communication service (Personal Communication Service, PCS) phone, a cordless phone, a Session Initiation Protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA) and other devices.

Optionally, the terminal device may also be a smart watch, a tablet computer, or other device.

[0040] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0041] Figure 2 FIG. 1 is a flow chart of a method for processing a secondary cell beam failure in an embodiment of the present application. The method for processing a secondary cell beam failure in this embodiment can be applied to Figure 1 Terminal devices in Figure 2 As shown, the method comprises the following steps:

[0042] S110: When a beam failure occurs in a secondary cell, determine at least one first candidate beam in the secondary cell.

[0043] In the NR system, the cells where the terminal device works include the primary cell and the secondary cell, where the primary cell is responsible for radio resource control communication with the terminal device, and the secondary cell is used to provide additional radio resources. The number of primary cells where the terminal device works is usually one, and the number of secondary cells can be multiple, that is, the terminal device can work in multiple secondary cells at the same time.

[0044] In this step, the secondary cell where the beam failure occurs is the secondary cell in which the terminal device is currently working.

[0045] When a beam failure occurs in a secondary cell, the terminal device determines at least one first candidate beam in the secondary cell where the beam failure occurs, wherein the first candidate beam is a beam corresponding to the secondary cell where the beam failure occurs.

[0046] Optionally, the number of secondary cells where beam failure occurs is one or more. When the number of secondary cells where beam failure occurs is one, the terminal device executes the secondary cell beam failure processing method of the present application based on the secondary cell; when the number of secondary cells where beam failure occurs is multiple, the terminal device executes the secondary cell beam failure processing method of the present application based on each secondary cell.

[0047] Optionally, the at least one first candidate beam may specifically include all beams corresponding to the secondary cell where beam failure occurs.

[0048] S120: Obtain parameter measurement results of reference signals corresponding to each first candidate beam.

[0049] The parameter measurement result of the reference signal is used to characterize the performance information of the first candidate beam.

[0050] After determining at least one first candidate beam, the terminal device further obtains a parameter measurement result of a reference signal corresponding to each first candidate beam, so that the terminal device can determine the performance of each first candidate beam based on the parameter measurement result of each first candidate beam.

[0051] S130: Send beam failure processing information according to the parameter measurement result.

[0052] After obtaining the parameter measurement results of the reference signal corresponding to each first candidate beam, the terminal device sends beam failure processing information based on the parameter measurement results corresponding to all first candidate beams.

[0053] Optionally, the terminal device may be a network device corresponding to the terminal device (eg Figure 1 The access network device in the terminal device sends beam failure processing information so that the network device can perform corresponding beam failure processing according to the beam failure processing information sent by the terminal device.

[0054] The secondary cell beam failure processing method provided in this embodiment, when a beam failure occurs in a terminal device, determines the candidate beam of the secondary cell, obtains the parameter measurement result of the reference signal of the candidate beam, and then sends beam failure processing information to the corresponding network device according to the parameter measurement result, so that the network device can perform corresponding beam failure processing based on the beam failure processing information. Thus, the present application can solve the problem of the lack of corresponding processing specifications for secondary cell beam failure in the prior art, and can perform corresponding beam failure processing when a beam failure occurs, thereby improving the stability of the NR system.

[0055] In one embodiment, the reference signal (RS) includes a synchronization signal block (SSB) and / or a channel state information reference signal (CSI-RS).

[0056] Among them, the synchronization signal block SSB refers to the signal sent by the network equipment in the NR system to the terminal equipment for the terminal to perform synchronization, system information acquisition, measurement and other operations.

[0057] Specifically, the synchronization signal block SSB contains the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH). The primary synchronization signal and the secondary synchronization signal are mainly used to help the terminal device identify the cell and synchronize with the cell. The physical broadcast channel contains the most basic system information such as the system frame number, the timing information within the frame, etc. The successful reception of the synchronization signal block SSB by the terminal device is a prerequisite for its access to the cell.

[0058] When the network device communicates with the terminal device through multiple beams, the network device may send multiple synchronization signal blocks SSB on the multiple beams. For example, the network device uses N beams to send the N synchronization signal blocks SSB, where each of the N beams is used to send one synchronization signal block SSB.

[0059] Correspondingly, the terminal device receives multiple synchronization signal blocks SSB sent by the network device, each synchronization signal block SSB corresponds to a beam, and the terminal device can measure the synchronization signal block SSB to determine the optimal one or more receiving beams as the working beam.

[0060] The channel state information reference signal CSI-RS is mainly used for channel measurement in the LTE system.

[0061] Specifically, in the NR system, the channel state information reference signal CSI-RS is mainly used for: (1) obtaining channel state information for scheduling, link adaptation, and transmission settings related to MIMO (Multiple-Input Multiple-Output); (2) for beam management, obtaining the beam shaping weights of the terminal device and the network device, and supporting the beam management process; (3) for accurate time-frequency tracking, which is achieved by setting the TRS (Tracking Reference Signal) in the system; (4) for mobility management, the system obtains and tracks the channel state information reference signal CSI-RS of the current cell and the neighboring cell to complete the measurement requirements related to the mobility management of the terminal device; (5) for rate matching, the rate matching function at the RE (Resource Element) level of the data channel is completed by setting the zero-power channel state information reference signal CSI-RS.

[0062] Optionally, in this embodiment, the reference signal may only use the synchronization signal block SSB, that is, the terminal device determines the performance of the beam based on the parameter measurement results of the synchronization signal block SSB.

[0063] Optionally, in this embodiment, the reference signal may only use a channel state information reference signal CSI-RS, that is, the terminal device determines the performance of the beam according to the parameter measurement result of the channel state information reference signal CSI-RS.

[0064] Optionally, in this embodiment, the reference signal can simultaneously use the synchronization signal block SSB and the channel state information reference signal CSI-RS, that is, the terminal device comprehensively determines the performance of the beam based on the parameter measurement results of the synchronization signal block SSB and the parameter measurement results of the channel state information reference signal CSI-RS.

[0065] In this embodiment, the terminal device can more accurately determine the performance of each beam based on the parameter measurement results of the synchronization signal block SSB and / or the channel state information reference signal CSI-RS, thereby facilitating subsequent beam failure processing.

[0066] In one embodiment, the parameter of the measurement result includes any one of a reference signal receiving power (RSRP), a reference signal receiving quality (RSRQ), and a signal interference noise ratio (SINR).

[0067] The reference signal received power RSRP is the linear average of the received power (in watts) on the resource elements carrying the reference signal on the measurement frequency bandwidth considered, and is a measure of signal strength. The reference signal received power RSRP may specifically be the layer 1 reference signal received power (Layer 1 Reference Signal Received Power, L1-RSRP).

[0068] The reference signal received quality RSRQ is the ratio of the reference signal received power RSRP to the received signal strength indicator (RSSI), that is, the reference signal received quality RSRQ is the difference between the reference signal received power RSRP and the received signal strength indicator RSSI in dB.

[0069] The signal to interference plus noise ratio SINR refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). The signal to interference plus noise ratio SINR may specifically be the layer 1 signal to interference plus noise ratio (Layer 1 Signal to Interference plus Noise Ratio, L1-SINR).

[0070] Specifically, in this embodiment, any one of the above three parameters can be selected as a parameter to obtain a parameter measurement result corresponding to the reference signal.

[0071] For example, when the reference signal is a synchronization signal block SSB, if the reference signal received power RSRP is selected as a parameter, the reference signal received power RSRP measurement result of the synchronization signal block SSB is obtained; if the reference signal received quality RSRQ is selected as a parameter, the reference signal received quality RSRQ measurement result of the synchronization signal block SSB is obtained; if the signal interference and noise ratio SINR is selected as a parameter, the signal interference and noise ratio SINR measurement result of the synchronization signal block SSB is obtained.

[0072] For another example, when the reference signal is a channel state information reference signal CSI-RS, if the reference signal received power RSRP is selected as a parameter, the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS is obtained; if the reference signal received quality RSRQ is selected as a parameter, the reference signal received quality RSRQ measurement result of the channel state information reference signal CSI-RS is obtained; if the signal to interference and noise ratio SINR is selected as a parameter, the signal to interference and noise ratio SINR measurement result of the channel state information reference signal CSI-RS is obtained.

[0073] Optionally, when a synchronization signal block SSB and a channel state information reference signal CSI-RS are simultaneously selected as reference signals, the parameter types corresponding to the two reference signals are the same, that is, both signals measure the same type of parameters.

[0074] For example, when the synchronization signal block SSB and the channel state information reference signal CSI-RS are selected as reference signals at the same time, the reference signal received power RSRP can be selected as a parameter to obtain the reference signal received power RSRP measurement result of the synchronization signal block SSB and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS.

[0075] It can be understood that when the synchronization signal block SSB and the channel state information reference signal CSI-RS are selected as reference signals at the same time, the reference signal reception quality RSRQ or the signal to interference and noise ratio SINR can also be selected as a parameter to obtain the corresponding measurement result.

[0076] Optionally, after obtaining the parameter measurement results of the two reference signals, the method further includes a step of normalizing the parameter measurement results of the two reference signals.

[0077] Specifically, first, the weight coefficients corresponding to the synchronization signal block SSB and the channel state information reference signal CSI-RS are preset. After obtaining the reference signal received power RSRP measurement result of the synchronization signal block SSB and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS, the reference signal received power RSRP measurement result of the synchronization signal block SSB and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS are weighted and summed according to the weight coefficients corresponding to the synchronization signal block SSB and the channel state information reference signal CSI-RS, so as to obtain the final reference signal received power RSRP measurement result.

[0078] For example, set the weight coefficient corresponding to the synchronization signal block SSB to a, the weight coefficient corresponding to the channel state information reference signal CSI-RS to b, the reference signal received power RSRP measurement result of the synchronization signal block SSB to A, and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS to B. Then the calculation formula for the final reference signal received power RSRP measurement result Y is: Y=a*A+b*B.

[0079] Optionally, the type of parameter to be used may be selected according to the actual application scenario. For example, in the MU-MIMO (Multi-User Multiple-Input Multiple-Output) scenario, the signal to interference and noise ratio SINR is preferably selected as the parameter, and in other cases, the reference signal received power RSRP may be preferably selected as the parameter.

[0080] In this embodiment, the terminal device can more accurately determine the performance of each beam based on the reference signal received power RSRP measurement result / reference signal received quality RSRQ measurement result / signal to interference and noise ratio SINR measurement result of the reference signal, thereby facilitating subsequent beam failure processing.

[0081] In one embodiment, the secondary cell beam failure processing method further includes a processing step of determining whether a beam failure occurs in the secondary cell.

[0082] Figure 3 Schematic diagram of determining whether a beam failure occurs in a secondary cell in an embodiment of the present application, such as Figure 3 As shown, the processing steps for determining whether a beam failure occurs in the secondary cell specifically include S102 to S108.

[0083] S102, obtaining a parameter measurement result of a reference signal corresponding to a current beam in a secondary cell;

[0084] S104, determining whether a parameter measurement result of a reference signal corresponding to the current beam is less than a second preset threshold;

[0085] S106: When the parameter measurement result of the reference signal corresponding to the current beam is less than a second preset threshold, determining that a beam failure occurs in the secondary cell;

[0086] S108: When the parameter measurement result of the reference signal corresponding to the current beam is greater than or equal to the second preset threshold, determine that no beam failure occurs in the secondary cell.

[0087] Among them, the current beam is the beam currently used by the terminal device.

[0088] The second preset threshold is a pre-set threshold for determining whether a beam failure occurs. The second preset threshold can be expressed as threshold-failure (failure threshold). It can be understood that the value of the second preset threshold can be different for different parameter types. For example, when determining whether a beam failure occurs, the second preset threshold corresponding to the reference signal received power RSRP and the second preset threshold corresponding to the signal to interference plus noise ratio SINR are different, and can be specifically set accordingly based on different parameter types.

[0089] Optionally, when the reference signal is a synchronization signal block SSB, a block error rate (BLER) may also be used to determine whether a beam failure occurs. When the block error rate is used as a parameter, the principle of determining whether a beam failure occurs in a secondary cell is different from the principle of determining whether a beam failure occurs in a secondary cell when the reference signal received power RSRP is used as a parameter.

[0090] Specifically, the terminal device obtains the block error rate measurement result of the synchronization signal block SSB, and determines whether the block error rate measurement result is greater than a preset threshold. If the block error rate measurement result is greater than the preset threshold, it is determined that a beam failure has occurred in the secondary cell; if the block error rate measurement result is less than or equal to the preset threshold, it is determined that no beam failure has occurred in the secondary cell.

[0091] In this embodiment, the terminal device can determine whether a beam failure occurs in the secondary cell by comparing the parameter measurement result of the reference signal of the current beam with the second preset threshold, and then execute the secondary cell beam failure processing method when a beam failure occurs in the secondary cell to ensure the stability of the NR system.

[0092] In one embodiment, sending beam failure processing information according to parameter measurement results includes: if the parameter measurement results of all first candidate beams are less than a first preset threshold, sending beam failure processing information according to a first preset strategy.

[0093] The first preset threshold is a value less than the second preset threshold, and the first preset threshold can be specifically expressed as threshold-discard. When the parameter measurement result is less than the first preset threshold, the beam can be considered to be in an unavailable state. At this time, the terminal device sends beam failure processing information according to the first preset strategy.

[0094] Optionally, the sending of beam failure processing information based on the measurement results of the reference signal corresponding to the at least one first candidate beam specifically includes: if the duration during which the parameter measurement results are less than the first preset threshold reaches a preset duration, a first message is sent through the main cell where the terminal device is located, and the first message is used to notify the network device that the secondary cell is unavailable.

[0095] When the parameter measurement results of all first candidate beams are less than the first preset threshold, the terminal device and the network device cannot communicate through the beam. At this time, the terminal device further confirms whether the secondary cell can be demodulated based on the duration that the parameter measurement results are less than the first preset threshold.

[0096] Specifically, if the duration during which the parameter measurement results are less than the first preset threshold reaches the preset duration, it means that the beam performance is extremely poor and the secondary cell cannot be demodulated. At this time, the terminal device cannot communicate with the network device through the secondary cell. Therefore, the terminal device sends a first message to the network device through the main cell where it is located. Based on the first message, the network device can determine that the secondary cell is currently unavailable.

[0097] Further, after the duration during which the parameter measurement results are all less than the first preset threshold reaches a preset duration, the terminal device confirms that the secondary cell cannot be demodulated, and thus can disconnect from the secondary cell to avoid wasting network resources.

[0098] Optionally, sending beam failure processing information based on the measurement results of the reference signal corresponding to the at least one first candidate beam specifically also includes: if the duration during which the parameter measurement results are less than the first preset threshold does not reach the preset duration, sending a second message through the main cell where the terminal device is located, and the second message is used to notify the network device that there is no available beam in the secondary cell.

[0099] When the parameter measurement results of all first candidate beams are less than the first preset threshold, the terminal device and the network device cannot communicate through the beam. At this time, the terminal device further confirms whether the secondary cell can be demodulated based on the duration that the parameter measurement results are less than the first preset threshold, thereby confirming whether communication can be restored.

[0100] Specifically, if the duration during which the parameter measurement results are less than the first preset threshold does not reach the preset duration, it means that the beam performance is poor, but the secondary cell can restore communication through demodulation. At this time, the terminal device can continue to disconnect from the secondary cell and send a second message to the network device through the main cell where it is located. Based on the second message, the network device can determine that the secondary cell currently has no available beam, that is, there is no new beam identified (NBI).

[0101] In one embodiment, beam failure processing information is sent according to parameter measurement results, including: if there is a beam in the first candidate beams whose parameter measurement results are greater than or equal to a first preset threshold, and the parameter measurement results of all first candidate beams are less than a second preset threshold, then the beam failure processing information is sent according to the second preset strategy.

[0102] When the parameter measurement results of all first candidate beams are less than the second preset threshold, the terminal device cannot communicate with the network device through the secondary cell. At this time, if there is a beam with a parameter measurement result greater than or equal to the first preset threshold in the first candidate beam, the performance of the beam with a parameter measurement result greater than or equal to the first preset threshold is poor, but the secondary cell can perform demodulation to restore communication. At this time, the terminal device sends beam failure processing information according to the second preset strategy.

[0103] Optionally, sending beam failure processing information according to the measurement result of the reference signal corresponding to the at least one first candidate beam includes: sending a second message through the main cell where the terminal device is located, and the second message is used to notify the network device that there is no available beam in the secondary cell.

[0104] At this time, the terminal device can continue to disconnect from the secondary cell and send a second message to the network device through the primary cell where it is located. Based on the second message, the network device can determine that the secondary cell currently has no available beam, that is, there is no new beam indication.

[0105] In one embodiment, sending beam failure processing information according to the parameter measurement result includes: if there is a second candidate beam in the first candidate beams whose parameter measurement result is greater than or equal to the second preset threshold, and the parameter measurement results of all the first candidate beams are less than a third preset threshold, sending the beam failure processing information according to the third preset strategy;

[0106] Among them, the third preset threshold is a value greater than the second preset threshold, and the third preset threshold can be specifically expressed as threshold-failure-ad. If there is a second candidate beam in the first candidate beam whose parameter measurement result is greater than or equal to the second preset threshold, but the parameter measurement results of the second candidate beam are all less than the third preset threshold, it can be considered that the performance of the second candidate beam is good. At this time, the terminal device sends beam failure processing information according to the third preset strategy.

[0107] Optionally, sending beam failure processing information according to the measurement result of the reference signal corresponding to the at least one first candidate beam includes: sending a beam failure recovery request through the main cell where the terminal device is located.

[0108] Specifically, when there is a second candidate beam in the first candidate beam whose parameter measurement result is greater than or equal to the second preset threshold, but the parameter measurement results of the second candidate beam are all less than the third preset threshold, the terminal device sends a beam failure recovery request through the primary cell where it is located, and the beam failure recovery request is used to notify the network device that it can perform beam failure recovery on the terminal device based on the second candidate beam, so that the terminal device and the network device can communicate again through the secondary cell.
